History
![[10 MHz] 3D Ultrasonography Reveals - *Note* Ultrasonography reveals an open funnel retinal detachment (white arrow). Note the echolucent vitreous humor. The posterior choroidal detachments (black arrows) exhibit variable internal reflectivity consistent with blood. A = anterior, S = superior, T = temporal.](https://eyecancer.com/wp-content/uploads/2016/05/case111.gif)
Unlike static 2D images, a 3D volume can be rotated, oriented, and sectioned. This movie allows the viewer to review 5 (out of hundreds of possible) sections of this 3D ocular volume.
The original 3D block was composed of 90 sequentially acquired 2D images reconstructed into a 9.5 megabyte file. Due to limitations of the Internet, the entire file (volume) is not displayed. While evaluating this animation, you are experiencing a retrospective review of the ultrasound examination and realizing the potential of telemedicine.

Comment
This case presents two of the many unique capabilities of 3D ultrasonography:
- The ability to quarter the acquired volume and thereby image 3 planes (3 dimensions) simultaneously.
- The ability to replay the examination in a remote location (as you are doing in limited form). This capability will allow ultrasound specialists to review and comment on examinations performed in remote locations.
